Case Study: Lounge Underwear achieves 25% lower CPA and 177% increase in website traffic with AdRoll

How a Fast-Growing Brand Builds a Holistic Customer Experience

Lounge Underwear is a UK‑born direct‑to‑consumer brand built on the "Comfort Made Sexy" ethos that has rapidly expanded since 2015 into 11 localized markets and global shipping. As the business scaled (and demand surged during the pandemic), Lounge faced the challenge of moving beyond retargeting to a full‑funnel strategy that would drive new customer acquisition while preserving brand values across international markets.

Lounge partnered with AdRoll (Retargeting, Brand Awareness) and Shopify Plus to deploy dynamic display and video ads, countdown timers, localized creative testing, and a plug‑and‑play Shopify integration for fast market launches. The campaign lifted performance dramatically: average CTRs around 1.5% with an 82% YoY CTR increase on Black Friday, a 25% improvement in CPA, and a 177% rise in website traffic versus 2019/20 while ad spend grew only 146%—proving more efficient, scalable growth and faster audience expansion.
